It was previously revealed that in contrast to the Kaiju seen in Pacific Rim, Pacific Rim Uprising’s Kaiju will be more intelligent.
A new wave is Kaiju is on the way, and this time, their plans are more specific.
As Uprising star John Boyega described it, the first wave of Kaiju were a “test run,” and even though that particular breach was closed at the end of Pacific Rim, it’s not the only way these creatures can come to Earth.
Uprising director Steven DeKnight also stated that much like how humans have been improving the Jaegers over the last 10 years, the aliens that control the Kaiju have been “tinkering and upgrading” the monstrosities.
